Initial analysis

The property at 1840-1842 Clement Street is a two-story, multi-family residential building with commercial space, constructed in 1911 and currently owned by the Hu Lenox Family Trust. The building underwent significant transformation in 2011-2012, transitioning from a former restaurant to a stained glass workshop, which included substantial renovations such as new storefronts, structural support modifications, and the installation of new skylights. During this period, various infrastructure improvements were completed, including water pipe replacement, electrical upgrades (installing lighting, switches, receptacles, smoke detectors), plumbing work (including bathroom remodels and area drains installation), and HVAC improvements with a new furnace installation.

Of particular concern is a complaint filed in July 2020 regarding the converted commercial space, raising questions about fire safety systems (specifically sprinklers), ventilation concerns related to fume management, and compliance with setback laws, though this complaint is currently listed as not active. The building's maintenance history shows regular responses to street cleaning and graffiti issues, particularly in 2022, with multiple 311 calls for general cleaning and graffiti removal, suggesting ongoing exterior maintenance challenges. Recent building improvements included street space permits and utility work, though there appears to be a lapse in permit status for some plumbing and electrical work from 2012. A historical fire complaint from 2009 was resolved on the same day, with conditions corrected.

Risk rating

How 1840-1842 Clement St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Out of 2250 buildings in this neighborhood, 1890 are predicted to be safer.
